Specification of Letters Patent.

Patented Sept. 8, 1908.

Application filed February 28, 1907. Serial No. 359,808.

' ticularly to rope clamps or guy clamps, and

the objects of the invention are to improve upon the construction ofsuch devices, and increase their efficiency of operation, withsimplicity of parts, which are cheap to manufacture.

Another object of the invention is to enable the ropes to be moresecurely clamp-d between the parts than heretofore.

Further objects of the invention will hereinafter appear, and to theseends the invention consists of aguy clamp for carrying out all of theabove objects embodying the features of construction, combination ofelements, and arrangement of parts having the general mode of operationsubstantially as hereinafter fully described and claimed in thisspecification, and shown in the accompanying drawings in which Figure 1:is a side elevation of the clamp embodying the invention; Fig. 2 is avertical section of the same, on the line :z-a; of Fig. 1

Fig. 3 is a side elevation of a modification of the guy clamp, and Fig.4 is a vertical section on the line y-' of Fig. 3.

According to this invention the guy clamp comprises three parts, a bodymember or jaw A, a securing memberjor bolt B, and a nut C or C. The bodymember or jaw A is preferably provided with flat parallel faces D and E,and a single central longitudinal hole F entirely surrounded by thematerial of the jaw A. One of the faces of said jaw A is provided withtransverse grooves G at each side of the central hole F for thereception of the ropes H to be clamped.

Either the bolt B or nut C is provided with transverse grooves J adaptedto register with the grooves G and cooperate therewith to clamp theropes H.

In Figs. 1 and 2 the flat head K of the bolt is provided with grooves Jon its under side and the screw-tlreaded shank L of the bolt is adaptedtobe passed through the central jaw. It will be seen that the under sideof the bolt head is adapted to lie in proximity to the jaw withouttouching the same. Preferably, both sets of grooves G and J both in Fig.1 and in the modification in Fig. 3. are

curved as shown more particularly in the sectional views. 'Preferablythese grooves G and J are curved in planes lying substantially parallelto the axis of the shank of the bolt, in this instance the grooves Jbeing concave, while the grooves G are convex. According to thisconstruction, the ropes are clamped more firmly. in position than if thegrooves were straight.

In Fig. 3 the shank L ofthe bolt is adapted to be inserted through theaperture F from the opposite side of the jaw A to that in which it isinserted in Fig. 1, so that the head K of the bolt lies against the jaw.The nut C in this instance is provided with the grooves J whichcooperate with the grooves G of the jaw A.

I am not to be understood as limiting the invention to the formsof guyclamps shown, for the device may be embodied in widely varying formswithin-the scope of the apended claims. The invention contemplates,owever, a simple form of guy clamp comprising three essential arts,whereby the guy ropes may be clamper directly between and against anytwo of said parts.

I claim and desire to obtain by Letters Patent the following:

1. A guy clamp comprising in combination 'with cooperating curvedtransverse grooves adapted to lie at each side of the shank ofthe bolt,whereby guy ropes may be clamped directly between said two groovedparts.

2. A guy clamp comprising in combination three parts only, first, a bodymember or jaw having fiat parallel faces, and a single centrallongitudinal hole entirely surrounded by the material of the jaw, one oftheta-cos of said jaw being provided with curved transverse grooves ateach sideof the central hole, secondly, a securing member or bolt havinga 5 the jaw, the under side of the olt head beingfiat head, a shank ascrew -threaded end, against the bolt head and jaw, and thirdly,'

" the shank ofthejbplt being passed Kthrhugh -& nut on thescrew-threaded shank ofuthe the central hole in the jaw, and theheadofbolt for tightening and holding the parts.

the bolt lying opposite the rooved fece of 'In testlmony whereof I havesigned this specification in the presence of two subscriblng wltnesses.
